Problem:
The client is building a headless application and needs REST API documentation for handling posts, custom posts, taxonomies, and custom taxonomies with language filtering.
Solution:
If you're experiencing this, we recommend using the WordPress REST API to retrieve taxonomy terms. To get the list of terms for a taxonomy, use the following endpoint:
https://yoursite.com/wp-json/wp/v2/{taxonomy-slug}To get the list of terms for a taxonomy in a specific language, append the language parameter:
https://yoursite.com/wp-json/wp/v2/{taxonomy-slug}?lang={lang_code}For example, to get categories in German:
https://yoursite.com/wp-json/wp/v2/categories?lang=de
Refer to the WordPress REST API Taxonomies documentation for more details.
To retrieve posts from a category based on language, you can use the
filter hook within a loop to get the translated post ID. Here's an example code snippet:
$args = array(
'post_type' => 'post',
'tax_query' => array(
array(
'taxonomy' => 'category',
'field' => 'slug',
'terms' => 'bob',
),
),
);
// The Query.
$the_query = new WP_Query( $args );
// The Loop.
if ( $the_query->have_posts() ) {
echo '<ul>';
while ( $the_query->have_posts() ) {
$the_query->the_post();
$my_post_id = get_the_ID();
$my_post_id = apply_filters( 'wpml_object_id', $my_post_id, 'post', false, 'fr' ); //get the post ID in French
echo '<li>' . esc_html( get_the_title( $my_post_id ) ) . '</li>';
}
echo '</ul>';
} else {
esc_html_e( 'Sorry, no posts matched your criteria.' );
}
// Restore original Post Data.
wp_reset_postdata();
For more information, refer to the wpml_object_id hook documentation and the WP_Query Taxonomy Parameters documentation.
